NEC Article 525 encompasses electrical protection requirements for carnivals, circuses, fairs, and similar events. In more detail, it has to do with the protection requirements of the portable wiring and other portable electrical equipment that comes with any of these outdoor traveling venues. We will be looking at the extension of this article, subset 525.23 and its branches, in more detail. NEC article 525.23 has 4 different parts, which include:

A.) Stipulating where GFCI protection is required. This part states that all equipment needs to follow NEC article 210.8(B), and in addition protection is required with:

1.) All 125-volt, single-phase, 15- & 20-Amp non-locking type receptacles used for disassembly and reassembly or readily accessible to the general public.

2.) Equipment that is readily accessible to the general public and supplied from a 125-volt, single-phase, 15- or 20-Amp branch circuit
